Thanks Guys, that was quick. I am not sure of the stud pattern other than it is a five stud. It has what look like Vintique wheels with two patterns ie 10 holes. I will measure up at the weekend and see if I can work it out. I will do some more research on the 67-69 Camaro route to see what I can come up with. I sent the pics to Real Steel to see if they could help but no reply yet.
Now I need to find out what carb I have on the 305 so I can rebuild it, some old single barrel leaky thing, might be best to replace with a four barrel and a manifold, but I'll save that for another post.
Came with an English MOT but lots to do to pass our Isle of Man test, oh well spanners ahoy!
